12s

Hi Fuse 18 (I think) is marked as 25a fuse Trailer in the fuse box. Currently the other end (ISO connection in bumper vent) has nothing connected with just a standard 12n connection. Did Mercedes give any specification on this circuit which they deliberately included for 12v trailer use...

We need to get a 12S socket added to our E320 estate - is there anything unusual about the wiring on a '94 model to bear in mind when getting it fitted??? Thanks.
